38 S&W Ammo For Sale

In 1877, Smith & Wesson introduced .38 S&W (9x20mm) ammunition designed for its “First Model,” a single-action, spur-triggered revolver. Introduced in the 1850s, metallic cartridge revolvers became an overnight success. Most were either large caliber guns or pocket pistols that used .22 or .32 short loads. The .38 offered more power than the previous rounds, making it more appealing to the military as well as the general public.

The U.S. Cavalry field-tested the .38 S&W, which was officially adopted as a service cartridge by Great Britain, most of her former colonies, and Israel during its war for independence. Countless law enforcement departments in the U.S. and around the world also adopted the cartridge.

The .38 S&W is also known as .380 Rim, .38 New Police, Belgian 9mm Revolver, and .38 S&W Corto. Despite its similarities, the round should not be confused with the .38 Special. Due to its shape and diameter, it is also not interchangeable with the .38 Special. For a detailed breakdown of these differences, see our comprehensive 38 Special vs 38 S&W comparison.
